Abstract
The present disclosure discloses a touch circuit, a touch substrate and a touch display device. The touch circuit includes a light sensing module arranged corresponding to a touch area and configured to, when the touch area receives light which meets a first preset condition, transmit a first signal transmitted via a signal input line as a sensing signal to a processor through a first sensing signal transmission line and a second sensing signal transmission line, respectively. The processor determines position information of the touch area based on a first sensing signal transmitted via the first sensing signal transmission line and a second sensing signal transmitted via the second sensing signal transmission line.
